A boat is heading towards a lighthouse, whose beacon-light is 102 feet above the water. From point A, the boat's crew measures the angle of elevation to the beacon, 13, before they draw closer. They measure the angle of elevation a second time from point B at some later time to be 22. Find the distance from point A to point B. Round your answer to the nearest tenth of a foot if necessary. Thank you

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
